Description

i 149768in 149768

Opfindelsen angår en råplade for en bygningsplade fremstillet efter oprulningsmetoden, hvilken råplade indeholder malede cellulose- og/eller affaldsfibre, som bærefibre for dens vådmasse, gips som bindemiddel og som øvrige komponenter 5 hydraulisk hærdende cement, armeringsfibre og tilsaetningsstoffer.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a raw board for a building board made by the roll-up method, which contains ground cellulose and / or waste fibers, as carrier fibers for its wet mass, gypsum as binder, and as other components, hydraulic hardening cement, reinforcing fibers and additives.

Ifølge belgisk patentskrift nr 876.407 kendes en fremgangsmåde til fremstilling af en råplade for en bygningsplade på gipsbasis, som ikke indeholder asbest, ved oprulningsmetoden, hvilken råplade beregnet på den sam- -10 lede tørstofvægt indeholder 70*-95% gips som halvhydrat og til en formalingsgrad på 30-70°SR (Schopper-Riegler) nedbrudte cellulosefibre og/eller tilsvarende affaldspapir samt herudover armerings*- og fyldst0ffibre-;samttilsætningsstof fer.According to Belgian Patent Specification No. 876,407, a method of making a raw board for a gypsum-based building board which does not contain asbestos is known by the roll-up method, which raw board, based on the total dry matter weight, contains 70% -95% gypsum as a semi-hydrate and for a grinding degree of 30-70 ° SR (Schopper-Riegler) decomposed cellulose fibers and / or similar waste paper, as well as reinforcing * and filler fibers;

15 Med den nævnte fremgangsmåde har man dog ikke kunnet fremstille sådanne plader med ønsket kapacitet. Årsagen hertil har vist sig at være massens dårlige tilpasningsevne, dvs., at den har en tendens til at udvise egenskaber snarere som en væske med lav viskositet end en fast masse. Massens fil-20 treringsegenskaber er heller ikke tilfredsstillende, hvilket betyder, at for meget fast stof absorberes med vandet til oprulningsmaskinens (Hatschek) filt og ledes derfra med vandet bort fra processen. Stof, som bliver siddende i filten forkorter ligeledes maskinens anvendelsestid, hvilket 25 fører til et for stort antal driftstop.However, with the said method, such plates of the desired capacity have not been produced. The reason for this has been found to be the poor adaptability of the mass, i.e., it tends to exhibit properties rather than a low viscosity liquid rather than a solid mass. Also, the filtration properties of the pulp are not satisfactory, which means that too much solid is absorbed with the water to the felt of the reeling machine (Hatschek) and passed from there with the water away from the process. Fabric that remains in the felt also shortens the machine's service life, leading to an excessive number of downtime.

Ved forskellige forsøg på at undgå nævnte ulemper har man fundet, at pladen ifølge opfindelsen, der fremstilles ved at der til gipsmassen sættes en ringe mængde hydraulisk hærdende cement i højst 30% af den samlede vægt af massens tørstof, 30 således overraskende kan fremstilles ved en fremgangsmåde med en ønsket høj kapacitet. Man har ligeledes fundet, at det bortledte vand herved er renere, at antallet af driftstop falder, og at filtens levetid stiger. Massen udviser ligeledes en til sin struktur ønsket fast kvalitet. Resultatet er betydeligt 149768 2 bedre end fremgangsmåde ifølge det nævnte belgiske patentskrift nr. 876.407.In various attempts to avoid said disadvantages, it has been found that the sheet according to the invention produced by adding to the gypsum a small amount of hydraulically curing cement in not more than 30% of the total weight of the dry matter of the pulp, can thus be surprisingly produced by a process with a desired high capacity. It has also been found that the drained water is thereby cleaner, that the number of downtime falls and that the life of the felt increases. The mass also exhibits a solid quality desired for its structure. The result is significantly better than the method of the aforementioned Belgian Patent Specification No. 876.407.

Forholdet mellem gips, cement og cellulosefibre i kendte plader 5 fremgår af det følgende:The relationship between gypsum, cement and cellulose fibers in known plates 5 is as follows:

Fra finsk fremlæggelsesskrift nr. 64.935 er det kendt at anvende 10-80% cement som bindemiddel og gips i form af semihydrat, som dog i· praksis omdannes fuldstændigt til dihydrat inden 10 vådmassen, samles til en plade. Ifølge den foreliggende patent ansøgning udgør gipsen det vigtigste bindemiddel. Gipsen er desuden i form af semihydrat i råpladen. Cement anvendes blot i en ringe mængde, 10-30%, og dets opgave er således ikke at fungere som et egentlig bindemiddel, men det anvendes til 15 at forbedre egenskaberne af den fra det belgiske patentskrift nr. 876.407 kendte plade.From Finnish Patent Specification No. 64,935, it is known to use 10-80% cement as a binder and gypsum in the form of semihydrate, which, however, in practice is completely converted to dihydrate before the wet mass, is assembled into a plate. According to the present patent application, the plaster is the most important binder. The plaster is also in the form of semihydrate in the raw board. Cement is used only in a small amount, 10-30%, and its task is thus not to act as an actual binder, but it is used to improve the properties of the sheet known from Belgian Patent No. 876,407.

Ved fremgangsmåden ifølge det finske fremlæggelsesskrift nr.By the method according to the Finnish publication no.

64.935 åbnes cellulosefibrene slet ikke, medens cellulose-20 fibrene ifølge den foreliggende patentansøgning åbnes til 20-80° SR, hvilket er af overordentlig betydning for opnåelse af en god råplade. Ifølge opfindelsen kan man på grund af den lille cementmængde indeslutte en betydelig mængde gips i råpladen.64,935, the cellulose fibers are not opened at all, while the cellulose fibers of the present patent application are opened to 20-80 ° SR, which is of great importance for obtaining a good raw plate. According to the invention, due to the small amount of cement, a considerable amount of gypsum can be enclosed in the raw sheet.

2525

Ved fremgangsmåden ifølge det belgiske patentskrift nr. 881.381 blandes det hydrauliske bindemiddel med fibre, vand og eventuelle andre tilsætningsstoffer til slam. Som hydraulisk tilsætningsmiddel anvendes eksempelvis cement eller gips. I patent-30 skriftet vises det derimod ikke således, som det sker i den foreliggende patentansøgning, at man ved anvendelse af gips som bindemiddel desuden skal anvende en ringe mængde cement, * hvis opgave er at forbedre råpladens egenskaber. Cellulosefibre ne males ifølge det belgiske patentskrift nr. 881.381 sammen 35 med sulfatopløsninger, som hæmmer behandlingen, og formalingsgraden, som ikke er nævnt, findes at være lavere end 20-80° SR.In the process of Belgian Patent Specification No. 881,381, the hydraulic binder is mixed with fibers, water and any other sludge additives. As a hydraulic additive, for example, cement or plaster is used. In the patent specification, on the other hand, as is the case in the present patent application, it is not shown that when using gypsum as a binder, a small amount of cement must be used, the task of which is to improve the properties of the raw plate. The cellulose fibers are ground according to Belgian Patent Specification No. 881,381 together with sulphate solutions which inhibit the treatment, and the degree of milling which is not mentioned is found to be lower than 20-80 ° SR.

149768 - 3 I det schweiziske patentskrift nr. 368.740 beskrives ikke baerefibre af formalede cellulosefibre, hvis formalingsgrad skulle være 20-80° SR og heller ikke armeringsfibre op til 20% af tørvægten af råpladens tøremne. Det nævnte patentskrift 5 angår en speciel opsamlingsmetode, som ikke tager hensyn til bærerfibreproblematikken. Ifølge patentskriftet kan man foruden gips (krav 3) anvende gips-slaggecement som bindemiddel i en mængde, som ikke nævnes. Eftersom cellulosefibrene hensigtsmæssigt ikke åbnes, og der anvendes gips-slaggecement som 10 bindemiddel og således ikke i særlig små mængder til at forbedre pladens egenskaber, beskrives ikke den opfinderiske tanke, som ligger til grund for den foreliggende patentansøgning, dvs. bestemmelsen af den korrekte åbningsgrad for cellulosefibrene i forhold til den anvendte ringe mængde cement og 15 afvejningen heraf i forhold til gipsmængden. Gips-slaggecementen er desuden ubestemt med hensyn til sammensætningen.149768 - 3 Swiss Patent Specification No. 368,740 does not disclose ground fibers of milled cellulose fibers, the degree of milling being 20-80 ° SR, nor reinforcing fibers up to 20% of the dry weight of the raw sheet drying material. Said patent specification 5 relates to a special collection method which does not take into account the fiber-fiber problem. According to the patent, in addition to gypsum (claim 3), gypsum slag cement can be used as a binder in an amount not mentioned. Since the cellulose fibers are conveniently not opened and gypsum slag cement is used as a binder and thus not in very small quantities to improve the properties of the sheet, the inventive idea underlying the present patent application, i.e. determining the correct degree of opening of the cellulose fibers in relation to the small amount of cement used and the trade-off thereof in relation to the amount of gypsum. Furthermore, the gypsum slag cement is indeterminate in composition.

Tysk offentliggørelsesskrift nr. 2.336.220 angår ved støbning og presning fremstillede byggeplader, hvorved de problemer, 20 som er forbundet med opsamlingsmetoden ifølge den foreliggende opfindelse ikke findes. Således er cellulosefibrenes åbningsgrad overhovedet ikke defineret. Ifølge det tyske skrift anvendes gips som bindemiddel. Derudover kan man (jvf. krav 6) anvende cement i en mængde, som er mindre end 10%, hvilket er under 25 den i den foreliggende patentansøgning definerede mængde.German Patent Specification No. 2,336,220 relates to molded and pressed building boards, whereby the problems associated with the collection method of the present invention do not exist. Thus, the degree of opening of the cellulose fibers is not defined at all. According to German writing, plaster is used as a binder. In addition, (cf. claim 6), cement may be used in an amount less than 10%, which is less than the amount defined in the present patent application.

Ifølge tysk offentliggørelsesskrift nr. 2.649.300 fremstilles et pladeformet materiale, specielt karton-, pap- og bygningsplader, hvori gips indgår i form af dihydrat. Ifølge ansøgningen 30 undgås specielt en sådan fremgangsmåde, hvor gipsen har form af semihydrat, såsom i råpladen ifølge den foreliggende patentansøgning. Cellulosefibrenes formalingsgrad er heller ikke ' defineret, og i eksemplerne, som beskriver fremstillingen af bygningsplader, anvendes der forskellige harpikser som 35 bindemiddel. Af beskrivelsen fremgår alment, at både organiske og uorganiske bindemidler kommer på tale ved fremstillingen af plader.According to German publication specification No. 2,649,300, a sheet-shaped material, especially cardboard, cardboard and building boards, is made, which contains gypsum in the form of dihydrate. In particular, according to the application 30, such a method is avoided in which the gypsum is in the form of semi-hydrate, such as in the raw board according to the present patent application. The degree of grinding of the cellulosic fibers is also not defined, and in the examples describing the manufacture of building boards various resins are used as binder. It is generally apparent from the description that both organic and inorganic binders are involved in the manufacture of sheets.

Ved forsøg/ som udføres på pladerne ifølge opfindelsen, har det desuden overraskende vist sig, at pladernes fugtbestandighed, bøj-5 ningsstyrke, stivhed og overfladehårdhed er øget mere end ventet. Desuden falder korrosionsvirkningen, når massens pH-værdi stiger. Disse fordele har man opnået uden at miste den ved anvendelse af gips forbedrede brandsikkerhed af plader fremstillet efter oprulningsmetoden, hvor malede 10 cellulosefibre anvendes som bærefibre.In addition, when carried out on the sheets according to the invention, it has surprisingly been found that the moisture resistance, bending strength, stiffness and surface hardness of the sheets have increased more than expected. In addition, the corrosion effect decreases as the pH of the mass increases. These advantages have been achieved without losing the improved fire safety of boards made by the roll-up method, in which painted 10 cellulose fibers are used as carrier fibers.

Ad eksperimentel vej har det vist sig, at et optimalt resultat i høj grad afhænger af cellulosefibrenes rette nedbrydningsgrad i forhold til den foreliggende cementmængde, hvilket igen ret nøje bør afpasses i forhold til gipsmængden.By experimental route, it has been found that an optimal result depends to a large extent on the proper degree of degradation of the cellulose fibers in relation to the present amount of cement, which in turn should be carefully adjusted to the amount of gypsum.

15 Opfindelsens kendetegn fremgår af det efterfølgende patentkrav. Ifølge dette krav indeholder råpladen 30-80 vægt% gips i CaS04, 1/2 H20-form, 10-30% hydraulisk hærdende cement, 3-30% til fomalingsgraden 20-80°SR nedbrudte cellulose- og/eller affaldspapirfibre samt andre bestand-20 dele ialt i sådanne mængder, som fremgår af patentkravet.The features of the invention are set forth in the following claim. According to this requirement, the raw board contains 30-80% by weight of gypsum in CaSO4, 1/2 H20 form, 10-30% hydraulic curing cement, 3-30% to the degree of grinding 20-80 ° SR decomposed cellulose and / or waste paper fibers and other components -20 parts in total in such quantities as can be found in the claim.

Den hydraulisk hærdende cement kan f.eks. være Portland cement.The hydraulic hardening cement can e.g. be Portland cement.

I den efterfølgende tabel vises resultater af sammenligningsforsøg. Af den første vandrette linie fremgår det 25 resultat, som opnås for en bygningsplade med en sammensætning ifølge beskrivelsen til belgisk patent- nr.The following table shows results of comparison experiments. The first horizontal line shows 25 results obtained for a building board with a composition as described in Belgian patent no.
